The wheel has a tire on it(you do ride with tires on your wheels,right?). The weight of the tire contributes to the mass of the wheel in the real world,because you can't ride a bike without them. Discussing the wheel by itself is pointless.

Ah,that's my problem. I was 15 when I started high school(10th grade for SAHS). If you were in high school at age 12,you must've been a genius. I bow to your knowledge,and will leave the thread.
